Google has a new form of encryption called Adiantum that’s designed to bring storage encryption to cheaper Android devices without impacting performance.
The majority of Android hardware is currently encrypted using the AES standard, but more affordable phones, such as those equipped with low-end processors built around the ARM Cortex-A7, for instance, lack AES hardware support.
Google says that Adiantum is five times faster than Android’s typical AES encryption on low-power devices. Nerds can read all the juicy details about the evolution of the new encryption mode in this blog post.
Adiantum is scheduled to be released with Android Q, the successor to Android Pie that’s due later this year. Don’t expect the new technology to speed up flagship devices however; Google says that AES is still the faster encryption standard when hardware support exists, and will continue to be a requirement for phones that support it.
